STOP-ACTION FOB AGCORDIONS.

Application filed November 27, 1916.

To aZZw ham it may concern Be it known that EUGENIO GALIZI and ADRIANQ GALIZI, both subjects of the King of Italy, and both residing at 124 Mulberry street, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Stop-Actions for Accordions, of which the following is a specification.

The purpose of the present invention is to provide improvements in accordions and the like, in a manner such that certain tones of said instrument may becontrolled at will without removing the hand of the player from the key-board of the accordion. With accordions made at present it is necessary for the player to remove his hand from the key-board and pull or push a certain lever in order to obtain a change in the tones of the accordion, thereby causing a great inconvenience to the player.

Referring to the drawing hereto annexed, in which the same letters and numerals are used to designate the same parts or corresponding details of construction, Figure 1 is a detailed plan view of the stop action mechanism and Fig. 2 is a perspective view of a portion of said mechanism, showing one of the cogged sliders in connection with the end of the sliding rod which is attached to the push-bar. In the drawing 1 is a pushbar which is located at the edge and perpendicularly to the plane of the key-board of the accordion, rods 2, 3 and 4 are in the same plane and perpendicular to the pushbar 1, said rods 3 and 4 act as guides so as to prevent push-bar 1 from rotating about rod 2 as its axis, rod 2 is held free to slide by the sleeve 5 which is permanently fastened to the accordion. Near the end of rod 2, two spiral springs 6 and 7 are located, one end of each being fastened to the rod 2 and the other ends to the accordion so that when the push-bar 1 is pushed down and then released the springs 6 and 7 will push it up again. Also near the end of the rod 2 a pin 8 is located perpendicular to the plane formed by the rods 2, 3 and 4. VVhenthe push-bar 1 is pushed down it in turn pushes down pin 8, said pin 8 will fall into the groove 9 and it therefore will push down the cogged slider 10, which in turn by means of the cogged end 11 will rotate cogged wheel 12, wheel 12 being free to rotate about axle 12 cogged wheel 12 in turn by means of cogs 13 Will. slide slider 14, it will also slide up- Specification of Letters Patent.

ward by means of cogged end 16, theother' cogged slider 15 in a way such that the groove 17 will be at the point where groove 9 was before push-bar l was pushed down.

By pushing said push-bar 1 again pin 8 will fall into groove 17 and therefore push down cogged slider 15, thereby revolving cogged wheel 12 in the opposite direction,

hence sliding 14 to its original position.

Cogged sliders 10 and 15 are held in position and guided by the plate 18 and the respectlve screws 19 and 20 which are confined 1n the respective openings 21 and 22, also by the respective spiral springs 23 and 24. Each end of said springs is fastened and free to rotate by the respective screws 25, 26, 27 and 28 and eachof the other ends 29 and 30 are inserted in the respective holes 31 and 32 in sliders 11 and 15. Briefly by pushing down push-bar 1 it will slide cogged slider 10 and therefore revolve cogged wheel 12 to the left, which in turn will slide 14' also to the right, when 1 is released the groove 17 will occupy the point originally held by groove 9 hence when 1 is pushed down again it in turn pushes down cogged slider 15 and therefore revolves cogged wheel 12 to the right, hence sliding 14 back to its original position, by repeatedly push ing down 1, 14 will be slid to the right or left accordingly.

Having now described our invention what we claim, and desire to secure by Letters Patent ofthe United States is 1. In a stop action for accordions the combination of wire springs, a push-bar having at its lower surface three rods, the outer ones acting as guides and the center one having a pivot at its lower end, the wire springs being attached to said rod in a way such that the rod and therefore the pushbar will spring back when released, all substantially as set forth.

2. In a stop action for accordions, the combination of a push-bar having three rods attached to it, the center rod having a pin attached to its lower end, with two cogged sliders, one end of each of said cogged slidends of both cogged sliders, and a rack meshing with the lower side of said wheel. 3. In a stop action for accordions, the combination of a sliding rod having a pin at its lower end, two cogged sliders which of the cogged sliders, and a cogged strip are guided in a vertical plane by a small meshing with the lower side ofthe cogged' plate, and two screws which limit the mowheel substantially as set forth. r 7 tion of the upper part of each of said In testimony whereof we have aifixed our 5 cogged sliders, and two spiral springs which signatures in the presence of two witnesses.
